Retatrutide 30 mg

Retatrutide is a triple agonist. It activates GIP, GLP-1 and glucagon receptors at the same time — the most potent of the injectable weight-management peptides currently in research.

What it does

  • Appetite suppression across three receptor pathways
  • Supports metabolic rate alongside calorie reduction
  • Early research shows superior weight-loss outcomes vs dual agonists
  • Once-weekly dosing via the cartridge and reusable pen

How it's delivered
